Application filed June 21 188d." (Nomodclll To (1. ivhom it may concern:

Be it known that I, FRANK L. PALMER, of the city of New London, in thecounty of New London and State of Connecticut, have inyentedanew anduseful Mechanical Movement, of which thefollowing is a specification.

My new mechanical movementis more particularl y intended for producing the change in relative position between an implement or took-such, for example, asa molding or other ing-machine-and the article to be operated on by the implement or to0l such, for exam ple, as a piece'of wood on other material to be I 5. "quilted, or embroidered.

H .The'advantages oi' my ,invention are more "ap'parent'when such'change in relative posimolded or out. one pi ece of fabric tobe sewed,

tion between the implement ortool and the ElOflflilOlB to be operatedon is tozbe universal or of my mechanical movement" are a rack or in' any desired direction along lines either straight or curved. The necessaryjelements track arranged inpattern form; or, in other words',in any formcorrespon'ding to the lirfe or lines 'along.which the desired change in relative position is to beproduced, and a positively-operatingengaging device-suoh as a positivelyu'ot-ated pinion or wheel which acts upon the said rack or. track, one .of said parts being capable of bodily movement in direct ti ons transverse to each other, whereby provision is afforded for producing changes at uniform 'speed'in the relative position of the. rack ortrackl and engaging device by the action of the- .engaging.device*on the rack. or jtrack. To provide for thehodily movement capable of 'universalmovement.

and have no definite or positive movement imparted to them, the partor element of: the

in Fig. 4, and upon it is 'formed unsecured a pattern rack or track, B"that is, a rack or track arranged in pattern forn'l. This track or rack in pattern form constitutes one element of my movement.

Extending parallel with the track or rack B, and at a uniform distance therefrom, is a groove, a, which constitutes a guide, and the v purpose of which will be hereinafter explained. of the rack or track or the engaging device, I- employ two carriages movable in directions transverse to each othenand'one' mounted upon the other, and as both carriages are left free.

G designates, a wheeled carriagewhich runs upon track-rails b on the top of the frame A, and upon the lower or first carriage C is mounted a second or upper wheeled carriage,

C, which is movable along rails b on the carriage G in directions transverse to the line of movement of the carriage 0.1 The carriages 0 G, neither of them have any definite or pesitive movement, but each, is left entirely free, so that its 'speedor, directionof movement may be changed at any poi ut Without interfering'with the movement of the other. Either carriage may be stopped entirely and the speed .01 either of them'maybe increased or .movement of the other continued, and the l rack or track at a uniform speed, no matter,

In this example vice, which constitutes the second element of my new mechanical movement is carried by the second carriage, G, and, by its engagement with and action upon the pattern rack or track 13, is made to travel along the same.

that the positive operation,which it has of itself, produces its movement along the pattern what direction or what changes in direction are pursued.

The engaging device which is shown in this example of my invention consists of a small toothed wheel or pinion, D, which is carried on a shaft or upright noirrot-ary spindle, D, fitted to a bearing, 0, in the carriage C. As here show-n, theturning ofthe shaft or spindle D is prevented by a screw, (1, entering a; groove therein. The pinion or wheel D has secured to it or formed with it a pulley, e, and the upper end of the shaft D enters the groove or guide a. and so holds the pinion in engage-v ment with the track or rack B. The shaft D and pinion .l) are held up by a spring, e, arranged between the upper carriage, G', and a collar, 0 out-he shaft, and when it is desired to free the pinionfrom the pattern rack or' track and the end of the shaft from the guide or groove a all that is necessary is to pull said s.pring. I 4

In lieu of the toothed pattern-rack B here shown and the rotary pinion D, I may-employ and a smooth wheel, D*, engaging therewith. The wheel D may be faced or covered with rubber to increase its frictional engagement with the smooth pattern-track 13*. The pinion D has a positive rotary motion, and the means for rotating it must be of such a nature that the rotary motion will be imparted to it wherever it moves, by reason of its engagement with thepattern rack or track. The means more shown for this purpose consist of an endless belt or band, E, encircling the pulley e, and also passed one or more turns around a driving pulley, F, on the upper end ofian upright shaft, ,F. The belt or band is kept taut, and

which is movable upand down a guiderod, f, and 'WlllCll is hung in a depending loop of vice'versa, by pulleys or idler-sf, around which it passes, and when the engaging device is moved from side to side of the machine the belt or band will bedeficcted around and over an idler-pulley, f, or more than one idler, as may be necessary; y

G designates a stationary sewing-machine the upper arm, G, of which'ca-rries a needle ing-shaft, f The lower arm, G, of the sewingmachmc has at the end the usual work lite-or bed, f in which ashuttle, loopei or other stitch-forming device is operated by a shaft, f which receives its necessary motion by any usual or suitable means from the ma chine-operating shaft f Adriving-belt may be applied to fast and loose pulleys f" f* on a taeheda fabricfframe. As here shown, the

frame consists of bars gfl t o which opposite edges of a fabric, 8, may be secnred'by'clamp- .ingstrips 9*. or other suitable means, and after thus securing the opposite edges of the fabric 8 the two bars y" may be moved apart to put tension on the fabric; As'here shown, the bars 9 are provided at the ends with yoke's 4/, and by means of screws 9 may be adjusted toward and from each other. 7

From the above descriptionit-will be understood that by reasono'f the rotation of the pinion'D at a uniform speed and its engagement with the rack or track B, the hon-rotary shaft D will be moved at a uniform speed and in a direction corresponding tolthe pattern .of the rack or track. The fabric frame, being suspended and carried by the non rotary shaft or spindle-D, will be sihiilarly'moved, and the course of the fabric 8 under the needle of thesewing-machine G will conform tothe contour of the rack or track, and the speed of .movement of the fabric will be uniform. i

I will now describe the machine shown in Figs. 5 and 6, which in many respects is similar to the one already described. Two car,-

riagespG and C, are mounted upona frame-' work, A, and are movable along tracks or rails I) b in directions transverse to each other, as

before described. capable of free movement. riage, O, unlike the one before described, is not-arranged above the'first carriage, 0, al-
